Neural nAChRs PET imaging probes.

There have been a number of attempts to study PET radioligands for imaging nicotinic acetylcholine receptors (nAChRs) in the human brain, and the most successful tracers found are radioligands for imaging α4β2-nAChRs, which is the main cerebral nAChRs subtype. 11C-Nicotine and 2-[18F]FA have been ap
